vue实现简单瀑布流布局
vue简单实现瀑布流布局的一种方式（vue瀑布流组件），供大家参考，具体内容如下
vue中的瀑布流布局组件
需求：图片容器宽度固定，高度根据图片自适应，图片一行不能排列时候，换行依次从左往右排列。（瀑布流概念）
另外结合vue-lazy实现懒加载 （ npm i vue-lazyload --save-dev）
使用也很简单，在需要懒加载的img标签上将:src换成v-lazy
父组件传递数据：
waterfallData:[
{
e_img: "test.jpg",
// 图片
e_intro: "描述信息",
u_img: "test.jpeg",
// 标记图
u_name: "开发者"},
{
e_img: "test.jpg",
e_intro: "描述信息",
u_img: "test.jpeg",
u_name: "开发者"}
]
